ir-keytable - a swiss-knife tool to handle Remote Controllers.
ir-keytable [OPTION]... --device [/dev/input/event* device] ir-keytable [OPTION]... --sysdev [ir class (f. ex. rc0)] ir-keytable [OPTION]... [for using the rc0 sysdev]
ir-keytable is a tool that lists the Remote Controller devices, allows one to get/set IR keycode/scancode tables, test events generated by IR, and to adjust other Remote Controller options. Note: You need to have read permissions on /dev/input for most of the options to work.
-a, --auto-load=CFGFILE Auto-load a table, based on a configuration file. Only works with sysdev. -c, --clear clears the old table -d, --device=DEV ir device to control -D, --delay=DELAY Sets the delay before repeating a keystroke -k, --set-key=SCANKEY Change scan/key pairs -p, --protocol=PROTOCOL Protocol to enable (the other ones will be disabled). To enable more than one, use the option more than one time -P, --period=PERIOD Sets the period to repeat a keystroke -r, --read reads the current scancode/keycode table -s, --sysdev=SYSDEV ir class device to control -t, --test test if IR is generating events -v, --verbose enables debug messages -w, --write=TABLE write (adds) the scancodes to the device scancode/keycode table from the specified TABLE file -?, --help Prints the help message --usage Give a short usage message -V, --version print the v4l2-utils version Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options. Options can be combined together. The options arguments are: DEV the /dev/input/event* device to control SYSDEV the ir class as found at /sys/class/rc TABLE a file wit a set of scancode=keycode value pairs SCANKEY a set of scancode1=keycode1,scancode2=keycode2.. value pairs PROTOCOL protocol name (nec, rc-5, rc-6, other) to be enabled DELAY Delay before repeating a keystroke PERIOD Period to repeat a keystroke CFGFILE configuration file that associates a driver/table name with a keymap file
On success, it returns 0. Otherwise, it will return the error code.
To list all connected Remote Controller devices: ir-keytable To clean the keycode table and use a newer one: ir-keytable -c -w /etc/rc_keymaps/nec_terratec_cinergy_xs To append more codes to the existing table: ir-keytable -w /etc/rc_keymaps/nec_terratec_cinergy_xs To read the current keytable, on the second remote controller: ir-keytable -s rc1 -r
